JACOB HENRY POSTEL, OF KEARNEY, NEBRASKA.

PIPE-HANGER COUPLING.

Application filed July 13, 1909, Serial No. 507,394.

T 0 all whom it may concern:

Be it known that I, JACOB HENRY PosrnL, a citizen of the United States,residing at Kearney, in the county of Buffalo and State of Nebraska,have invented a new and use ful Pipe-Hanger Coupling, of which thefollowing is a specification.

The objects of the invention are, generally, the provision in amerchantable form, of a device of the class above described, which shallbe inexpensive to manufacture, facile in operation, and devoid ofcomplicated parts.

With these and other objects in view, which a perusal of thisspecification will reveal to those skilled in the art, the inventionconsists in the novel construction and ar rangement of parts hereinafterdescribed, delineated in the accompanying drawings, and particularlypointed out in that portion of this instrument wherein patentable novety is claimed for certain distinctive and peculiar features of thedevice, it being understood, that, within the scope of what hereinafterthus is claimed, divers changes in the form, proportions, size, andminor details of the structure may be made, without departing from thespirit or sacrificing any of the advantages of the invention.

Similar numerals of reference are employed to denote corresponding partsthroughout the several figures of the drawings.

In the accompanying drawings,-Figure 1 shows my invention in verticaltransverse section, parts being left in elevation; Fig. 2 shows theinvention in side elevation, the support wherewith the device isassembled, being shown in section; Fig. 3 shows the invention in sideelevation mounted in a slightly dititerent manner from the showing oi?Fig. 2. Fig. 1- is a side elevation of the device assembled with aneye-beam, auxiliary grips being introduced into the structure; and Fig.5 a bottom plan of the socket.

In carrying out my invention, 1 provide a socket 1, the side walls ofwhich are impert'orate. The socket 1 comprises a body 2 which is in theform of an inverted trustum out a cone, terminating at its lower end ina cylindrical neck The neck and the body Specification of LettersPatent.

are provided with an axial opening extend ing entirely through thesocket. The upper portion and the lower portion 5 of this opening arecircular in transverse section, the upper portion a being ofconsiderably less diameter than the lower portion 5, whereby is formedwithin the socket, a shoulder 7. The intermediate portion 6 of theopening, located adjacent the shoulder 7, is polygonal in transversesection.

The invention further includes a retaining member which is denotedgenerally, by the numeral 8. This retaining member 8 comprises athreaded shank projecting beyond the socket 1 and adapted to slide inthe upper portion 4: of the opening through the socket, and to registersomewhat closely therein. The shank 9 terminates in a polygonal head 10which is adapted to register in the polygonal intermediate portion 6 or"the opening through the socket, against rotation therein.

The lower portion 5 of the opening in the socket is threaded, as denotedby the numeral 11. These threads 11 extend the entire length of the neck3 and throughout a portion of the body 2. The threads 11 terminate,however, at a distance below the lower end of the intermediate portion 6of the opening, slightly greater than the thickness of the head 10 ofthe retaining element 8. The threads 11 are adapted to receive the upperextremity of a threaded member 12 which may be in the form of a piece ofpipe, the lower extremity of which is threaded to fit in the collar 15of a ring 14, the ring 1% being adapted to support the pipe line.

In applying the device, a bar may be introduced through the ring 14:, orthe member 12 may be grasped by a pipe wrench, and the device rotated,the polygonal intermediate portion (3 of the opening in the socketengaging the head 10 of the retaining member 8, causing the shank 9 tobe advanced into the support with which the device is assembled. Owingto the fact that the threads 11 terminate below the lower end of thepolygonal portion 6, the socket 1 may he slid upward upon the shank 9 tocause the head 10 of the retaining member 8 to enter the. circularportion of the opening" in the socket which is disposed between theupper extremity of the member 12 and the lower extremity of theintermediate portion 6 of the opening through the socket. When the head10 is thus positioned, the socket 1 may be rotated upon the retainingmember 8 into any desired position, whereupon the head 10 may again bebrought to register against rotation in the intermediate portion 6 ofthe opemng.

I regard it as of importance that the socket 1 is of frusto-conicalform. By this construction, the socket is given a broad firm base,which, being brought into close relation with the ceiling, serves as aretaining plate to hold in place any portions of the plastering of theceiling which may have been loosened during the entrance of the threadedshank 9 thereinto.

Passing now to some of the specific applications of the device, I haveshown in Fig. 2, a ceiling 16 and a flooring 17 united by eye-beams 19between which is disposed concrete 18. When my invention is employed inconnection with the floor construction of the above described nature, anopening is made through the ceiling 16 into the concrete 18, and intothe opening thus formed, is introduced an expansion bolt 20 threadedupon its interior to receive the shank 9 of the retaining member, thebroad base of the body 2 bearing against the ceiling and holding it inplace, after the manner hereinbefore described.

In Fig. 3 I have shown a ceiling 21 spaced by beams 22 from a flooringcomprising the usual rough boards 23, upon which is superposed the fioorproper 24. hen my invention is used with this form of floorconstruction, the member 12 extends through the ceiling 21, theretaining member 8 passing through the rough boarding 23 and enteringthe floor proper 24, the base of the body 2 being in engagement with theportion 23 of the flooring.

In Fig. 4 my invention is shown assembled with an eye-beam 25. In suchinstance, I provide clips comprising body portions 27, the adjacent endsof which are arranged to overlap, as denoted by the numeral 28. One ofthese overlapping ends is bent to form a seat 29 adapted to receive theother end, whereby the upper faces of the body portion 27 of the clipsmay be disposed in flush relation. Through the overlapping ends 28 ispassed the upper extremity of the retaining member 8, a nut 30 beingmounted upon the retaining member 8 between the overlapping ends 28 andthe lower face of the eye-beam 25, the upper extremity of the retainingmember 8 being adapted to bear against the lower face of the eye-beam.The remote extremities of the body portions 27 of the clips are bentupwardly, and inwardly, toward each other, to engage the flange of theeyebeam. hen the socket 1 is rotated, the retaining element- 8 will beadvanced to engage the lower face of the eye-beam, whereby the upperends 26 of the clips may be drawn closely upon the flange of theeye-beam.

It will be seen from the foregoing illustration that the device is ofwide application. It is peculiarly serviceable in the case determined inFig. 3, in which the pipe line runs parallel with the joists 22. In suchcase it is frequently necessary to assemble the pipe-hanger with thelath and plastering of the ceiling, an uncertain and weak expedient.When the device of my invention is employed, the pipe-line need not besuspended from the fragile lath and lastering, but may be held securelyby the ooring, as shown.

when it is desired to remove the piping, referring particularly to Fig.3, the member 12 may be rotated out of engagement with the socket 1, thesocket being left in place. The apertures in the ceiling may then bepapered over, and, should it become necessary to replace the pipe-line,the member 12 may readily be inserted through the papering, and rotatedinto engagement with the socket which was left in place for itsreception.

The neck 3 of the socket serves to receive and to steady the member 12,the cylindrical form of the neck reducing the weight and consequentlythe cost of the socket; moreover, the cylindrical neck affords a meanswhereby, if desired, the socket may be grasped by a pipe-wrench forrotation.

Having thus described my invention what I claim as new and desire toprotect by Letters Patent is A pipe hanger comprising a socket withimperforate side walls, the socket including a body in the form of aninverted frustum of a cone terminating anteriorly in a cylindrical neck,of less diameter than the adjacent end face of the cone, the neck andthe body being provided with an axial opening extending entirely throughthe socket, the upper and lower portions of the opening being circularin cross section and the up per portion being of less diameter than thelower portion, whereby to form a shoulder within the socket, theintermediate portion of the openingfadjacent the shoulder, beingrendered polygonal; a retaining member having a threaded shank toregister slidably in the diminished portion of the opening and having apolygonal head to register against rotation in the intermediate portionof the opening, and to engage the shoulder against withdrawal, the lowerportionof the opening being threaded throughout the entire length of theneck and throughout a portion of the body, the threads terminating at apoint 161110Y8df10111 the lower end of the In testimony that I claim theforegoing intermediate portion by a distance slightly as my own I havehereto aflixed my signa- 10 greater than the thickness of the headlofthe I ture in the presence of two Witnesses. retaining member; athreaded e enient i w 7 i y T r) 'i w 9 adapted to engage at one end,the threads of J JLQOB IHLAR} I ObrlLL the opening; and pipe engagingmeans as- Vitnesses:
